Thomas Kantzos, the former Arlington police officer at the center of a steroid scandal, was sentenced Wednesday to one year and one day in a federal prison.

Kantzos, a 17-year veteran of the Arlington police force, was arrested in June and accused of accessing a police computer in December 2011 to get information to help a steroid dealer avoid arrest.

According to earlier reports, Kantzos had been buying steroids from the dealer for himself and other officers.

The investigation began in January 2013 after a man arrested for distributing anabolic steroids told authorities that he had sold steroids to Kantzos for five or six years, according to court documents.

The day Kantzos was arrested, fellow officer David Vo, who also was under investigation, committed suicide.

A third officer, Craig Hermans, resigned from the department in August after being placed on paid administrative leave during the investigation.

Kantzos was sentenced Wednesday by U.S. District Judge Barbara M.G. Lynn in Dallas.

In October, Kantzos pleaded guilty to exceeding access to a protected computer. He could have been sentenced to five years in prison.

An Arlington police spokesman declined to comment on the sentencing Wednesday.

In June, Police Chief Will Johnson told the Star-Telegram that the department would continue to work hard to keep the community’s trust in the wake of the steroid scandal.

“These actions were not consistent with our values and they are not tolerated within the organization,” Johnson had said.

Johnson announced that all employees would undergo random tests for drugs and other illegal substances, including steroids.

“Ninety-nine percent of the police employees are dedicated, hardworking public servants that want to make a difference in the community,” Johnson said in June. “They are sad. They are frustrated. They are disappointed that our department is being viewed through this lens because of the actions of a few.”
